WATER SAVING TOILET Filed Oct. 20, 1937 Patented Apr. 11, 1939 UNITED STATES PATENT FFICE 3 Claims.

This invention relates to toilet constructions and more particularly to a type of toilet which capable of use in homes which have no water supply piped into them.

One of the objects of the invention is to provide a toilet construction which may be easily and cheaply installed without great alteration to the building in which it is placed, and at the same time provide for convenient removal of waste material.

Another object of the invention is to provide means for conveying waste material to a septic tank or similar device and also to effectively seal said tank to prevent the escape of odors therefrom.

A still further object of the invention is to provide means for removing waste material from the building without causing any material loss of heat from the interior of said building.

Still a further object is to provide means automatically depositing charges of some suitable disinfecting and deodorizing chemical in predetery mined portions in conjunction with the operation of the remainder of the device. 2,5` These and other objects and advantages of the invention will more fully appear from the following description made in connection with the accompanying drawing wherein like reference characters refer to the same or similar parts throughout the views, and, in which:-

Fig. 1 is a vertical section through a portion of a building showing parts of the device in side elevation and other parts in vertical section;

Fig. 2 is a horizontal section taken approximately on the line 2-2 of Fig. l; and

Fig. 3 is an enlarged detail of the chemical dispensing valve arrangement.

In the particular embodiment of my invention disclosed in the drawing, there is shown a section 40 of a house side-wall 6 and a portion of a oor l. A cabinet-like structure 8 is shown against the side wall 6, the rear of the cabinet being open and registering with a similar opening in the side wall. The opening in the side Wall and the open rear of the cabinet are normally closed by a suitable insulated and weather stripped door 9 which is hinged along its upper edge at Ill. The top of the cabinet has an opening II therein and this opening is provided with an open seat I2 and hinged cover I3 of customary construction.

A waste receiving receptacle I4 is supported within the cabinet and is preferably of substantially conical shape as shown. The receptacle I4 is pivotally supported between a pair of spaced arms secured on opposite sides of the receptacle and above the center of balance of said receptacle. The arms I5 extend downwardly to and are rigidly secured to a cross shaft I6 which may be journaled in the side walls of the cabinet in suitable journals Il. One end of the shaft IS extends slightly beyond one of the side walls of the cabinet to receive an operating lever I8 conveniently positioned relative to the seat I2.

When the toilet has been used, movement of the operating lever I8 rearwardly from the forward position shown in Figs. l and 2 will cause rotation of the shaft I6 and rearward movement of the receptacle I4 with the arms I5. If the receptacle travels backwardly its lower portion will come into Contact with a trip I9 and cause the receptacle to tilt backwardly. At the same time that the receptacle is being moved backwardly the door 9 will be swung outwardly on its hinges by reason of the rods 2!! which are pivotally secured at opposite ends between the arms i5 and said door 9. Furthermore, a rope or chain 2i is connected between the outer face of the door 9 somewhat up from its lower edge and a small trap door 22 which is hinged at 23 and normally covers the open upper end of a pipe 24 which leads to a septic tank (not shown). Thus if the door 9 is swung outwardly it will engage the rope 2l and the small trap door 22 Will be opened so that contents of the receptacle I4 will be deposited in the pipe 24 as the receptacle is upset by the trip I9t A stop element 25 may be provided on the shaft I6 to limit the rearward movement of the receptacle I 4, and a similar but oppositely disposed stop 26 is provided to properly position the receptacle beneath the seat I2 when the operating lever I8 is moved to return said receptacle to its forward position. If desired a suitable housing 2l may be provided to enclose the door 9 and the upper portion of the pipe 24. A Ventilating pipe 28 communicates both with the interior of the cabinet and the interior of the housing 2l to carry off any odors within those two enclosures.

Mounted upon the cabinet and preferably against the wall of the building is a container 29 which is adapted to receive a supply of chemical preferably in powdered form. The container 29 is provided with a spout 30 and a tube 3Ua which leads from the spout to a position within the cabinet above the waste receptacle I4 when said receptacle is in its forward position. The container spout 30 is provided with a pair of spaced valve elements 3| and 32. These valves are operated by arms 33 and 34 whose outer ends are connected to a valve operating rod 35. This rod ex- Mii tends downwardly into the cabinet 8 and is secured to the outer end of the stop element 25 on the shaft I6. As the shaft I6 is rotated to move the receptacle supporting arms I5 and receptacle I4 rearwardly, the valve operating rod 35 will be drawn downwardly. As best shown in Fig. 3 when said rod is moved downwardly the upper chemical valve 3| will be opened and the lower valve 32 will be closed. 'I'his permits charges of chemical to come down into the spout 30 and be retained therein by the valve 32 when closed. When the waste receptacle I4 has been emptied and is returned to its forward operative position the Valve operating rod 35 will be moved to its upper position and the valves 3| and 32 will again be in the position shown in Fig. 3. This will permit the charge of chemical between the valves 3I and 32 to flow through the tube 30a and into the waste receptacle I4. Of course, if a liquid chemical is used it will be necessary to provide liquid seal valves but their operation in connection with the device will be generally the same.

From the foregoing it will be seen that I have provided a toilet structure which can be used without a water supply and in which the various operating parts and cooperating devices are moved in unison with a single operating lever, and wherein a fresh charge of chemical is 'automatically -deposited in the waste receptacle in measured amounts after each use of the toilet. The waste is removed from the cabinet and from the building and means is provided for preventing the escaping of heat from the interior of the building and odors are prevented from arising from the septic tank. My invention is particularly adapted for use in' farm homes where a supply of water is not readily available and can either be installed in a home when the latter is built or can be incorporated therewith after the home is constructed without any extensive alterations.

The conical shape of the waste receptacle I4 not only permits easy dumping of its contents, but also requires a smaller charge of chemical vthan would a cylindrical receptacle since the lower portion of said receptacle is of small cubic content.

It will, of course, be understood that various changes may be made in the form, details, ar rangement, and proportions of the Various parts without departing from the scope of my invention.

What is claimed is:

2. In a toilet construction, a cabinet having a seat formed therein, a receptacle adapted to be positioned beneath said seat, a pivot support for said receptacle adapted to swing said receptacle ba-ckwardly in said cabinet, a trip device adjacent the rear of said cabinet in the path of movement of said receptacle, a door in the rear of said cabinet, a connection between said receptacle support and said door to open said door when said receptacle and support are moved rearwardly, and waste receiving means positioned rearwardly of said trip device and said door` to receive the contents of said receptacle when said door has been opened and said receptacle has been moved backwardly and tilted by said trip.

3. In a toilet construction, a cabinet, a. shaft journalled in said cabinet and extending to the outer side thereof, an operating lever on the outer portion of said shaft, a pair of spaced arms in said cabinet extending upwardly from said shaft, a receptacle pivotally supported by said arms, a door at the rear of said cabinet, waste receiving means adjacent the rear of said cabinet, and a lever from said receptacle support to said door whereby movement of said operating lever will swing said receptacle backwardly and simultane-
